Firstly original voltage features are extracted from analog circuit with some components changing gradually; Then LDA is used to reduce the dimension of the original features to obtain effective features; In the following with the effective features of normal state, a DHMM trained by an improved training algorithm is applied to calculate KL distance to monitor analog circuit's state and evaluate its health. Applying this new method to an analog circuit, the experiment results show that the proposed method can successfully convert the unconspicuous change of early fault process into the obvious change of KL distance and owns excellent capability of state monitoring.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124080843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics of chemical corrosion effect on various stages of the complete stress-strain curve are analyzed. The law of the deformation and strength of sandstone corroded by different chemical solutions is obtained. The evolutionary neural network constitutive model is established to describe the stress-strain relationship of specimen by applying the theory of evolutionary computation and neural network. It is indicated that the evolutionary neural network constitutive model can better describe the mapping relationship between stress and strain of rockmass under chemical corrosion environments. The predicted results are in good agreement with the experimental results.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127692017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite considerable efforts for improving current approaches on GIS application development in recent years, there has been no specific attempt to solve this problem in an integrated manner, covering GIS applications interoperability and business alignment concerns together. This paper offers a high level approach with some useful patterns to overcome this challenge and introduce a minimum architecture for it. The key is to bring together the valuable unification of Service-Oriented Architecture (SOA) concepts and Open Geospatial Consortium (OGC) standards. The most obvious difference between this study and various activities which uses these two components together is evolving around the idea that SOA would not be considered as a utility for better GIS application development. SOA is considered as the base conceptual architecture in this study which not only solves the GIS development concerns but also meets real enterprise needs. Also the architecture tries to apply OGC specifications as much as possible for interoperability and agility concerns because of its common-acceptance in the GIS industry.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127750697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finally, we combine the documentation model with specific document format templates and generate the “requirements specification”, “preliminary design specification” and “detailed design specification”.

In general, millions of triangle meshes are used to model complicated biological tissues and irregular bioluminescent sources in virtual optical environment. Therefore, mesh simplification is very important for storage, transmission, process, and real-time rendering in molecular optical simulation. In this paper, a practical mesh simplification algorithm combining half-edge data structure and modified Quadric Error Metrics is introduced in detail, which has been successfully applied in our molecular optical simulation environment.

It has great influence on the performance parameters of Hall thruster. A Monte Carlo model on NWC is put forward in the paper. The electron is considered as test particle in the model and its initial velocity can be decided by a specific distribution function. Then electron current density due to NWC can be statistically obtained with the simulation results of a large number of electrons. Based on the Monte Carlo model, the relation between electrical field, magnetic field and electron current density due to NWC is calculated. The simulation result is well accordance with the experiment, which proves that the Monte Carlo model on NWC is valid. The Monte Carlo model on NWC provides a useful way to simulate the effect of some complicated factors lying in the real channel of Hall thruster on the electron current due to NWC. Therefore, some important physical phenomena in Hall thruster, such as sheath, channel wall material and shape, electron distribution function, magnetic field topology, have been briefly discussed in the end and the way considering these factors in Monte Carlo model is also presented. It makes possible to research the NWC phenomenon in detail.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126528725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serveral game theoretic model based dynamic spectrum sharing scheme were proposed to harmonize the system global utility and individual payoffs. Since DSAN users with limited rationality and selfishness adapt their behaviors to environmental dynamics gradually rather than quickly response to the change of environment as in traditional game, we focus on evolutionary features of the game process. We proposed a multistage dynamic spectrum sharing framework in which two stages are iterated. In Stage I, the centralized spectrum allocation is processed with the goal of getting interference free allocation with maximum system utilization. Stage II covers evolutionary spectrum trading and the evolutionary game based solution is extended to support global information and re-division of groups. Simulation shows the framework works well with dynamics of adaptation of users in DSANs, while achieving equilibrium for system utilities.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"8 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126002437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
